If Ben is 12 years older, and you have the info that three years ago, he was 4 times as old, then all you have to do is divide 12 by 4, giving you 3. You add 3 to that because it's been three years. You have your answer of 6.

Hope this helps! :)

Equivalent answers for 64 to the power of 2/3

madreJ [45]

Answer:

Step-by-step explanation:

Dealing with a fraction exponent on hand can be converted by using the fractional exponents rule where the fraction exponent is converted to something like this:

$64^\frac{2}{3} = \sqrt[3]{64^{2}}\\$

As you can see, the denominator of the fractional exponent is now the index of the radical. Here is a guide to know what goes where.

$64^\frac{x}{y} = \sqrt[y]{64^{x}}$

Both the original problem (64^2/3) and the converted formula can be put into a calculator.

Simplify (if you want to)

$\sqrt[3]{64^{2}}\\\sqrt[3]{4096}\\16$

64 to the power of 2/3 is 16.

a distributor wants to make 1000 pounds of trail mix that is 8% raisins. He will use a mix that is 5% raisins and a mix that is

leva [86]

Answer:

200 pounds 20% raisins

800 pounds 5% raisins

Step-by-step explanation:

Let number of 5% be x

and number of 20% be y

x + y = 1000

Also;

5% of x + 20-% of y = 8% of 1000 pounds

= 0.05x + 0.2y = 80

From i , x = 1000-y

0.05(1000-y) + 0.2y = 80

50-0.05y + 0.2y = 80

0.15y = 30

y = 200

x = 1000 - y

= 1000-200 = 800
